I tried another alternator for the 77 240D and it doesn't generate current either. There is no magnetic effect around the alternater when the car is running making me suspicious that there may not be power to the field coils. The two big wires have 12V but the small blue wire is dead. I would hate to buy a new alternator only to find that the problem is a bad lead. Does anyone know which alternator wire is for the field coil lead?
